PROP — Object Mechanics

Coordinate Category: Item Mechanics & Autonomous Object State
Alias: [OBJ]
Status: Tier 2 Specialized Directorial Coordinate


1. Purpose & Functional Role

[PROP] (or [OBJ]) commands autonomous object transformations, mechanical device states, physical hardware behaviors, kinetic item interactions, and state mutations of detached objects without conflating them with character anatomy.


2. Orthogonality & Scoping Boundary

  • In [ACT]: Character anatomical movement, hand tracking, grips, and physical handling of props (e.g., "John presses his thumb against the latch").
  • In [PROP]: The internal mechanical reaction, state mutation, or physics of the object itself (e.g., "the brass latch clicks open, spring-loaded lid popping upward").
  • In [AESTHETIC]: Static description and baseline wear of key props (e.g., Key Props: Antique bronze compass, scratched glass face).

3. Formatting & Syntax Rules

  • Header / Tag: [PROP] (or [OBJ]) on its own Sub-State in the Macro-State -> chain.
  • Description Style: Describe object mechanics, kinetic physics, surface deformation, structural changes, or hardware state:
    • [PROP] Vintage brass stopwatch lid snaps open, exposing spinning gold balance wheel
    • [PROP] Heavy iron padlock springs open with a mechanical jolt
    • [PROP] Revolver cylinder rotates one chamber clockwise and clicks into alignment
    • [PROP] Folded parchment tears along the center crease, splitting into two halves
    • [PROP] Ceramic teacup shatters on slate floor, spreading tea in irregular pool

4. Placement & Chaining in Macro-States

[PROP] is placed adjacent to the character action that triggers the mechanism or as a standalone object beat:

  • Action-Triggered Mechanical State: [CAM] MACRO CU -> [ACT] John's thumb pulls the antique hammer back -> [PROP] internal brass pawl clicks into half-cock position -> [AUDIO] sharp metallic ratchet
  • Autonomous Object Physics: [CAM] INS, low-angle -> [PROP] glass vial tumbles off table edge and shatters on flagstones -> [AUDIO] glass explosion and liquid splash
  • Prop State Handoff: [CAM 01] -> [ACT] Samira places bronze key on mahogany desk -> [PROP] key slides two inches across polished wood and comes to rest -> [AUDIO] metallic slide and tap
